Before the intrawebs was invented for people to shoot each other in the face online, games used to have this thing called a 'story'.
Some great classics and indie titles on offer.
Mostly adventure games, the at times dying at times reviving genre, but some puzzle-type games too.

Personal recommendations:
Really they're all good, but it's likely most people won't want to drop 54 USD on a bunch of adventure games.
To The Moon ; if you don't cry by the end of this game, see your local shaman, someone might have stolen your soul.
Gemini Rue ; well paced, well written & intriguing story that's easy to get caught up with.
The Longest Journey ; character models are pretty dated by today's standards, but this point n click game has great characters, voice acting & a memorable tale.
Dreamfall ; 'sequel' to The Longest Journey, but a straight up adventure game rather than point n click. Not without some gameplay hiccups but still superb story & characters.
Also I believe these two titles have never been cheaper before on GOG.
This is a pretty popular site.
